机械零件疲劳强度计算判别式和校核式的确定

The Derivation of Diseriminant and Checking Equation Which Calculates Fatigue Strength of Machine ELements

机械零件疲劳强度计算的关键是确定极限应力的大小,一般解法是在极限应力图上用图解法进行。本文推导出的数学判别式和校核式可直接用于判别和计算。

The Key to Calculate fatigue Strength of machine elements is to decide the size of ul-timate Strength . The general method is to express on the fatigue strength diagram the dis-eriminant and checking equation which is derived in this thesis can be used to distinguish and calculate directly.
